Bottle extractor for hollow glass moulding machines

Abstract

Bottle extractor for hollow glass moulding machines, of the type that have bottle handling fingers comprising, a head joined to a fixed position spin axis and which includes at least one fluidic action cylinder, whose rod is joined to the fingers, the head having a mobile head supporting the fluidic action cylinder(s); a head base joined to the fixed position spin axis and nut-screw means to move the mobile head with respect to the head base.

What is claimed is:  
     
       1. In a bottle extractor for hollow glass moulding machines, of the type comprised of bottle handling fingers, a head joined to a vertically oriented, fixed position spin axis shaft and which includes at least one horizontally oriented fluidic action cylinder, whose rod is joined at one end to the fingers, the improvement characterised in that the head is comprised of 
       a mobile head supporting the at least one fluidic action cylinder,  
       a head base fixed on top of a horizontally oriented table,  
       said table fixed on top of the fixed position spin axis shaft,  
       said head base positioned vertically above said shaft and said mobile head positioned vertically above said head base,  
       said mobile head enveloping said head base,  
       means for moving the mobile head horizontally with respect to the head base,  
       said means for moving said mobile head positioned in said head base and said mobile head,  
       said mobile head and said table protecting said means for moving from a contaminating atmosphere of said hollow glass moulding machine,  
       said at least one fluidic shaft is affixed to said mobile head and horizontally oriented and said rod of said at least one fluidic action cylinder extends horizontally outward from said moble head and said rod fixed such that the distance between the fingers and the mobile head is fixed.  
     
     
       2. The bottle extractor according to claim  1 , characterised in that the means for moving the mobile head with respect to the head base are nut-screw elements, the screw element positioned in the mobile head and the nut element positioned in the head base. 
     
     
       3. The bottle extractor according to claim  1 , characterised in that the mobile head is comprised of flaps which envelop the head base. 
     
     
       4. The bottle extractor according to claim  1 , characterised in that said head has a slip bushing which channels air from the shaft to the mobile head.
